Washington -LRB- CNN -RRB- -- Gen. Stanley McChrystal lost his job when Rolling Stone magazine ran an article in which some of his aides made disparaging remarks about the vice president and others . But a newly released investigation by the Department of Defense inspector general finds neither McChrystal nor any of his aides did anything wrong .

In the article called `` The Runaway General '' reporter Michael Hastings wrote that one of McChrystal 's aides referred to Vice President Joseph Biden as `` Bite Me '' and another referred to then-national security adviser Gen. James Jones as a `` clown . ''

After interviewing 15 people , the inspector general 's office completed its report on April 8 . It was made public Monday after a Freedom of Information Act request by the New York Times . Neither McChrystal , who cooperated with an earlier Army investigation , nor Hastings were interviewed for the inspector general 's report .

In the report , the inspector general writes , `` The evidence was insufficient to substantiate a violation of applicable DoD standards . '' The report goes on to say , `` Not all of the events at issue occurred as reported in the article . ''

It concluded `` none of the matters we reviewed warrant further investigation . ''

McChrystal , who had been in charge of all U.S. and International Security Assistance Force units in Afghanistan , was brought back to Washington after the article was published . After meeting with President Barack Obama , he resigned his command and later retired from the military .

But four days after the inspector general 's report was completed , the White House announced McChrystal would be part of the Michelle Obama 's and Jill Biden 's new Joining Forces initiative . The organization is set up to support and honor America 's service members and their families .

McChrystal is now a senior fellow at Yale University .
